20Pcs Diamond Burr Bits for Dremel, 1/8" Shank Rotary Tool Bits for Stone

Great for beginners. Value for money.

I had a nice set of salt and pepper shakers to match heirloom stone china, but they weren't used for years because the holes were too small. I researched videos and saw how some drill bits specialized for drilling ceramic-type materials are available, using water. I was able to enlarge the holes that were already there. Some cracking on the glaze occurred but otherwise it bore through and made a clean larger hole in seconds. I haven't tried some of the shaped bits that came with the set, but will be trying to smooth out some of the chips in older pieces I couldnt bare to throw out. These bits work on drummel tool and regular drills.

The diamond and coating rubs off too easily. You would need probably 3 sets to finish a medium project from lapis quartz or zoicite.

excellent selection of bits. I have been looking for years to find the right tool for manicuring my finger and toe nailsa nd the first one I tried from this set works perfectly. Used with care it trims the nail without abrading the skin.

I use these quite a bit, they wear fast but are cheap.

Works as described

Works good for softer stone. Keep the bits well lubricated during use. Clean when done using.

wish i could rate it a 0/10. i tried this product over many different materials. “ Carving, Engraving, Grinding, Stone, Rocks, Jewelry, Glass” is a LIE. i wish i could get a refund. but i tried so hard to make it work on all of my materials, that i passed the refund deadline. please don’t purchase this if you want any quality at all.

muy buenos

Funcionan excelente en pulido de vidrio, y se ajustan sin problema en la dremel 4000
